The heart is one of those organs that's really difficult to live without since it is responsible for moving blood throughout your body. In this lesson, we'll explore some of the issues that can happen to the heart and the cardiovascular system.

Important Respiratory Diseases: Obstructive, Restrictive & Infective

4. Important Respiratory Diseases: Obstructive, Restrictive & Infective

This lesson will discuss the different categories of respiratory diseases, including infectious, obstructive, and restrictive. Examples of each category will also be discussed.

Common Endocrine Diseases, Related Hormones & Their Effects

5. Common Endocrine Diseases, Related Hormones & Their Effects

This lesson discusses seven endocrine diseases as well as the hormones involved. Specifically, we explore diabetes mellitus, Addison's disease, Cushing's syndrome, hyperthyroidism, hypothyroidism, hyperparathyroidism, and hypoparathyroidism.

What are Genetic Disorders? - Definitions & Descriptions

6. What are Genetic Disorders? - Definitions & Descriptions

This lesson defines genetic disorders and explores three main types of genetic disorders, including monogenetic disorders, chromosome disorders, and multifactorial inheritance disorders. You'll learn about genes, chromosomes, DNA, and much more!

What are Neurological Disorders? - Definitions & Causes

7. What are Neurological Disorders? - Definitions & Causes

There are a ton of reasons for why your body's nervous system may fail. We'll go over what the nervous system is, what neurological disorders are, the many things that cause them, and what neurons and the myelin sheath have to do with all of this in this lesson.

Common Signs & Symptoms of Neurological Conditions

8. Common Signs & Symptoms of Neurological Conditions

Explore the differences between signs and symptoms and which signs and symptoms are commonly attributed to nervous system dysfunction and disease, including amnesia and ataxia.

Physiology of Adipose Tissue

9. Physiology of Adipose Tissue

Adipose tissue is a loose connective tissue that contains fat-storing cells. Learn how this tissue provides you with a long-term source of energy and cushions and insulates your vital organs, as well as how it may even act as an endocrine organ, in this lesson.
